CGVER-CAP LOCK.

Application filed February 28, 1925. Serial No. 12,433.

Y '0 all whom it may concern:

Be it known that I, HARRY J. Enrrs'r, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in a Cover-Cap Lock, of which the followii'ig is a specification.

This invention relates to anchor or at- 19 taching means for oil cup caps and the like and has for an object the provision of an inexpensive and positive cap anchor, to pre vent loss of said oil cup cap.

Another object is to provide an anchor means of this kind which is adapted to be disposed entirely within an oil cup or tank and is therefore normally out of sight and not liable to become broken or accidentally disconnected.

J- inother object is to provide an anchor or cap retaining means which is formed so to be of little value and use except that in the performance of its given function.

These and other objects are attained by the means described herein and. disclosed in the accompanying drawings, in which:

Fig. 1 is an elevational View of an oiler cup and valve partially in cross section and having embodied therein a cap anchor of my invention.

2 is a cross sectional view on line 2-2 of Fig. 1.

Fig. 3 is a plan view of the anchor of my invention.

Fig. 41- is a side view of the device shown in Fig. 3.

Fig. 5 is an elevational view of the device shown in Fig. 3.

Fig. 6 is a fragmental cross sectional view showing the relation of the cap and anchor of Fig. 1 when the cup is open.

H'eretofore it has been customary, to provide an oil cup and valve such as is shown in Fig. 1 with a cap anchor consisting of a key ring encircling a portion of the cap, a second key ring encircling a portion of the valve or the restricted part of the cup and to connect the two by means of a short section of chain in order that the cap might not become separated from the cup. However it is common for employees to remove the key rings for their personal use and thus the caps for lubricator cups frequently become separated from the cups and subse quently lost. The said anchor of my invention is so formed as to eliminate tennptation of an unauthorized employee to remove said anchor and carry it away with him. The anchor 7 is preferably made of a comparatively heavy steel wire such as steel music wire and is provided with a ring or single loop portion 8 formed intermediate its ends with the ends of the loop 8 bent at substantially right angles thereto as at 9 and formed into a pair of spaced parallel and curved arms 10, which are bent outwardly in opposite directions at 11 in order to provide hooks 12. The hooks 12 are adapted to lie in a plane substantially parallel to the ring or loop portion 8. "he anchors are adapted to be used for anchoring caps or plugs such as 13 to an oil cup such as 14:. The cap 13 may be provided with a threaded plug 15 having an integral perforated lug 1G. The plug 15 is adapted to engage in the threaded opening 17 of the cup 14 for sealing the cup. The body of the loop 8 of the anchor is adapted to be passed through the perforation in the lug 16 of the cap, the resiliency of the material permitting separation of the end portions of said loop at the points 9. The outermost ends of the hooks 12 are normally spaced a distance considerably in excess of the diameter of the threaded bore 17 in the cup. To insert the anchor into the bore, it is necessary to press the arms 10 together and to then insert one of the hooks obliquely through the opening 17 in the cup and to bring the points 11 together sufficiently to allow the remaining hook 12 to be passed through the opening. As soon as the anchor is released the arms will again assume their normal spaced relation and the hooks will therefore extend well beyond the sides of the threaded portion 17. Thus, as will be readily apparent from Figs. 1 and 2, the anchor is connected to the lug 16 within the cup and the anchor will remain suspended in said cup when the cap 13 is in its position as shown in Fig. 1. The cap may be freely turned for unscrewing the cap from the cup at which time the length of the arms 10 will permit withdrawal of the cap from the cup sutficiently to swing the cap clear of the threaded opening 17 in the cup. The curved shape of the arms 10 permits the cap to hang downwardly at the side of the cup while the books 12 preclude further movement of the cap and anchor. From the foregoing it will be readily apparent that the cap 18 may be freely manipulated without regard to the presence of the anchor and that as soon as the cap is free of its threaded engagement with the threaded opening 17 that the operator may release his hold upon the cap whereupon it will drop tree of: the opening in order to permit refilling of the cup. The curved arms 10 assume a position against the side of opening 17 leaving said opening unobstructed for filling purposes. In a like man ner, in closing the cup the cap is replaced without requiring any attention to the anchor which will readily drop into the cup 1% and assume its natural position.

\Vhat I claim is:

A cap anchor comprising a rod bent at its middle portion to form a ring, the free ends each being bent adjacent the ring at right angles to the plane of said ring to form parallel arms, said arms being curved and having formed at their ends oppositely disposed hooks parallel to the plane of the 25 ring portion.

In testimony whereof, I have hereunto subscribed my name this 25th day of February 1925.
